RESUMEN
Importance: The development of an alcohol use disorder in adolescence is associated with increased risk of future alcohol dependence. The differential associations of risk factors with alcohol use over the course of 8 years are important for preventive measures. Objective: To determine the differential associations of risk-taking aspects of personality, social factors, brain functioning, and familial risk with hazardous alcohol use in adolescents over the course of 8 years. Design, Setting, and Participants: The IMAGEN multicenter longitudinal cohort study included adolescents recruited from European schools in Germany, the UK, France, and Ireland from January 2008 to January 2019. Eligible participants included those with available neuropsychological, self-report, imaging, and genetic data at baseline. Adolescents who were ineligible for magnetic resonance imaging or had serious medical conditions were excluded. Data analysis was conducted from July 2021 to September 2022. Exposure: Personality testing, psychosocial factors, brain functioning, and familial risk of alcohol misuse. Main Outcome and Measures: Hazardous alcohol use as measured with the Alcohol Use Disorders Identification Test scores, a main planned outcome of the IMAGEN study. Alcohol misuse trajectories at ages 14, 16, 19, and 22 years were modeled using latent growth curve models. Results: A total of 2240 adolescents (1110 female [49.6%] and 1130 male [50.4%]) were included in the study. There was a significant negative association of psychosocial resources (ß = -0.29; SE = 0.03; P < .001) with the general risk of alcohol misuse as well as a significant positive association of the risk-taking aspects of personality with the intercept (ß = 0.19; SE = 0.04; P < .001). Furthermore, there were significant positive associations of the social domain (ß = 0.13; SE = 0.02; P < .001) and the personality domain (ß = 0.07; SE = 0.02; P < .001) with trajectories of alcohol misuse development over time (slope). Family history of substance misuse was negatively associated with general risk of alcohol misuse (ß = -0.04; SE = 0.02; P = .045) and its development over time (ß = -0.03; SE = 0.01; P = .01). Brain functioning showed no significant association with intercept or slope of alcohol misuse in the model. Conclusions and Relevance: The findings of this cohort study suggest known risk factors of adolescent drinking may contribute differentially to future alcohol misuse. This approach may inform more individualized preventive interventions.

BACKGROUND: This study aims to identify policy content challenges related to high-risk sexual behaviors, stimulant drugs, and alcohol consumption in Iranian adolescents. METHODS: This qualitative study analyzed high-level and national documents pertaining to adolescent health, high-risk sexual behaviors, stimulant, and alcohol consumption in adolescents. The documents, which were published by public organizations between January 1979 and February 2023 and publicly available, were complemented by interviews with policymakers and executives. The study involved reviewing 51 papers and conducting interviews with 49 policymakers and executives at the national, provincial, and local levels who were involved in addressing adolescent behaviors related to high-risk sexual behaviors, stimulant, and alcohol consumption. The data collected was analyzed using conventional content analysis. RESULTS: The study's results involved examining policy content and identifying challenges related to policy content. The analysis revealed that from the beginning of the Iranian revolution in 1979 until the late 1990s, the dominant approach in Iran was to deny the existence of high-risk behaviors among adolescents. However, in the early 2000s, the country began to adopt a new approach that acknowledged the social harms and ineffectiveness of previous strategies. As a result, a new policy framework was introduced to address high-risk behaviors among adolescents. The study's interviews with policymakers and executives identified 12 challenges related to policy content, including parallel programs, lack of institutional mapping, lack of evidence-based policymaking, lack of integrated approach regarding training, late parent training, lack of consideration of all occurrence reasons in adolescents' high-risk behaviors policymaking, and the existence of many abstinence policies regarding high-risk behaviors. CONCLUSIONS: The study's findings suggest that high-risk behaviors among adolescents in Iran are primarily a health issue, rather than a social or ideological one. Unfortunately, ideological approaches, stigma, and policymaking based on anecdotes rather than evidence have had a significant impact on this area. To improve policymaking in this domain, it is crucial to address these challenges by tackling stigma, adopting an integrated and holistic approach, and implementing evidence-based policies that consider all relevant aspects, including adolescents' subcultures and policy audiences. Such an approach can also be useful for other countries facing similar conditions.

Objectives. To assess the exposure of Chinese adolescents to proalcohol advertising and explore its association with alcohol consumption. Methods. A nationally and regionally representative school-based survey was conducted in mainland China in 2021 among students in grades 7 through 12, aged 13 to 18 years. We assessed adolescent exposure to proalcohol advertising and its association with alcohol consumption. Results. A total of 57 336 students participated in the survey, and the exposure percentage of proalcohol advertising was 66.8%, with no difference between boys and girls or between urban and rural areas. The top 3 exposure channels were television (51.8%), the Internet (43.6%), and outdoor billboards (42.0%). The exposure was higher among students who had consumed alcohol in the past 30 days (80.1% vs 65.1%; adjusted odds ratio [AOR] = 1.29) and in the past 12 months (77.3% vs 61.7%; AOR = 1.30). However, no significant correlation was observed between advertising exposure and drunkenness. Conclusions. Approximately two thirds of Chinese adolescents have been exposed to proalcohol advertising in the past 30 days, with television, the Internet, and outdoor billboards being the most prevalent channels. Exposure to proalcohol advertising exhibits a positive correlation with drinking. (Am J Public Health. 2024;114(8):814-823. https://doi.org/10.2105/AJPH.2024.307680).

BACKGROUND: This study aimed to investigate whether parental monitoring skills mediate the effect of hazardous parental alcohol consumption on adolescents' lifetime alcohol use. METHODS: This three wave longitudinal study was conducted with 884 families (n = 1,768 participants) to evaluate the effectiveness of a family-based drug prevention program for adolescents and parents across 12 Brazilian cities. We used structural equation mediation modeling to analyze the effect of hazardous parental alcohol consumption at baseline on adolescents' lifetime alcohol use at 12-month follow-up, mediated by parental monitoring skills latent dimension at 6-month follow-up. RESULTS: We found a significant indirect effect of parents' hazardous alcohol use on adolescents' alcohol use through parental monitoring (OR:1.18, 95%CI:1.02;1.36). CONCLUSION: Our finding underscores the importance of comprehensive preventive family alcohol approaches targeting adolescent alcohol use, which should consider both parental drinking behavior and monitoring practices.

PURPOSE: Driving after drinking is a preventable threat to public health. We examined the prospective association of adolescent-reported parental monitoring knowledge (PMK) with recurrent driving after drinking in emerging adulthood. METHODS: We analyzed six annual rounds (1-4, 6, 11) of the National Longitudinal Survey of Youth 1997 with a sample of 5,261 participants. PMK variables were created to recategorize parental monitoring measures by age of the youth. Recurrent driving after drinking was measured in 2002 and 2007 and dichotomized. Unadjusted and adjusted binary logistic regressions analyzed the association of PMK at ages 14, 15, 16, and 17 with recurrent drinking after driving in 2002 (ages 18-23) and 2007 (ages 22-28). Adjusted models included age, sex, race, household income, and education. RESULTS: Mother's PMK from ages 14 to 17 was inversely associated with recurrent driving after drinking in 2002 (adjusted odds ratios [AORs]: 0.89 [p = .003, age 14], 0.93 [marginal p = .062, age 15], 0.88 [p = .0003, age 16], 0.88 [p = .0003, age 17]). By 2007, the only significant association between mother's PMK and recurrent driving after drinking was for age 16 (AOR: 0.95, p = .017). For father's PMK, significant inverse associations were only found for ages 16 and 17 with 2002 recurrent driving after drinking (AORs: 0.93, p = .025 and .88, p = .0005) and age 15 (AOR: 0.95, p = .021) with 2007 recurrent driving after drinking. DISCUSSION: Adolescent perceived PMK appears to offer protection against recurrent driving after drinking in emerging adulthood. This protective effect appears to wane as youth reach their mid-twenties.

Negative life events (NLE) have been associated with increased alcohol use (AU) during adolescence. However, whether this risk association may be modified by leisure activities such as sports participation (SP) remains poorly understood. This study examined whether accumulated family-specific NLE in particular were associated with greater AU, and if so, whether SP moderated this association to reduce AU among high-NLE adolescents. We examined five annual assessments from a nationwide cohort of 3,422 Norwegian adolescents (13-15 year-olds; 55.3 % girls at baseline) who participated in the MyLife study. At each assessment, adolescents reported their AU on the Alcohol Use Disorders Identification Test-Concise (AUDIT-C), the number of family-specific NLE in the past 12 months, SP days in the past 30 days, and multiple sociodemographic and individual-level characteristics (covariates). Changes over time in AU as a function of NLE, SP, and their interaction (NLExSP) were examined with a set of partially nested growth curve models. AU increased non-linearly over time in all models. The fully adjusted best-fitting model showed significant NLExSP interactions (estimate = -0.013, 95% CI [-0.02, -0.006]), such that the initial AUDIT-C scores were lower for high-NLE adolescents with high SP and greater for high-NLE adolescents with low SP. Further, linear increases in AU over time were marginally steeper for high-NLE adolescents with high SP (NLExSPxTime estimate = 0.034, 95% CI [-0.0002, 0.007]). Thus, SP appeared to have a protective role in reducing AU for high-NLE youth primarily during middle school years. Prevention efforts thus may utilize organized sports for youth facing family-specific NLE as a resource early on.

OBJECTIVE: This study examined daily associations between alcohol use, cannabis use, and simultaneous alcohol and cannabis/marijuana (SAM) use with the likelihood of hooking up (uncommitted sexual encounter that may or may not include intercourse). METHOD: We used a longitudinal measurement burst ecological momentary assessment (EMA) design with 3-week EMA bursts with daily measurements repeated quarterly across 12 months. 1,009 (57 % female, Mean age = 20.00 [SD = 3.21]) Texan adolescents and young adults ages 15-25 participated in the study. Mixed effects logistic regression models were estimated using maximum likelihood estimation to evaluate the associations between substance use and hooking up. RESULTS: Within-person results indicated that participants were more likely to hook up on days with alcohol use and on days with cannabis use, but not on days with SAM use. Participants were also more likely to hook up on drinking days with higher-than-usual alcohol use. Between-person results indicated that participants who used alcohol more often or cannabis more often on average were more likely to hook up, and participants who tended to drink more on drinking days were more likely to hook up. CONCLUSIONS: Given the significant daily-level associations between alcohol and cannabis use and hooking up behavior, public health initiatives should focus on developing interventions to reduce alcohol and cannabis use and promote safer hooking up behavior among adolescents and young adults.

OBJECTIVE: Dual use of cannabis and alcohol has increased in adolescents, but limited research has examined how it relates to impaired driving or riding with an impaired driver (IDR) compared to single substance use. This study aimed to examine the odds of alcohol- and/or cannabis-IDR among adolescents based on their use of alcohol and/or cannabis, and whether associations differed by gender and age. METHODS: Cross-sectional survey data were used from a sample of 69,621 students attending 182 Canadian secondary schools in the 2021/22 school year. Multilevel logistic regression estimated the odds of exclusive alcohol-IDR, exclusive cannabis-IDR, and both alcohol and cannabis IDR (alcohol-cannabis-IDR). Substance use interactions with gender and age were tested. RESULTS: Overall, 14.7% of participants reported IDR; 7.5% reported exclusive alcohol-IDR, 3.2% reported exclusive cannabis-IDR, 4.0% reported alcohol-cannabis-IDR, and 7.4% were unsure if they had experienced IDR. The prevalence of IDR varied across substance use groups, 8.0% among nonuse, 21.9% among alcohol-only use, 35.9% among cannabis-only use, and 49.6% among dual use groups. Gender diverse, older, and students with lower socioeconomic status exhibited a higher likelihood of reporting alcohol-cannabis-IDR. Dual use was significantly associated with 9.5 times higher odds of alcohol-cannabis-IDR compared to alcohol-only use, and 3.0 times higher odds compared to cannabis-only use. Dual use was also associated with an increased likelihood of either alcohol- or cannabis-IDR. CONCLUSIONS: This study highlights that all students, regardless of substance use, are at risk of IDR, but students engaged in dual use of alcohol and cannabis face an elevated risk compared to both peers who do not use substances and those who use only a single substance. These findings emphasize the importance of targeted interventions that address the risks associated with IDR.

OBJECTIVE: The present study examined the independent and joint effects of bullying victimization and sexual harassment victimization on adolescent alcohol use over time within a community sample of adolescents. METHOD: Adolescents aged 13-15 years old at baseline (N = 800, Mage = 14.42, SD = 0.83; 57.5% female) recruited from Western New York State made five online survey reports of peer victimization and alcohol use over a 2-year period. Latent class growth analysis was used to identify trajectory classes of victimization from bullying and sexual harassment over time, and regression modeling was used to examine the associations with later alcohol use. RESULTS: Three developmental courses were identified for bullying victimization (moderate/decreasing, high/decreasing, never or low) and for sexual harassment victimization (moderate/decreasing, moderate/increasing, never or low). Adolescents in the moderate/decreasing group of bullying victimization subsequently consumed more alcoholic drinks when they drank. Belonging to the moderate/increasing group of sexual harassment was associated with increased later alcohol intoxication and number of drinks. Bullying victimization and sexual harassment victimization were concurrently correlated over time. Adolescents who followed the joint trajectory group of moderately decreasing bullying and increasing sexual harassment were more likely to report increased later alcohol intoxication and number of drinks. CONCLUSIONS: Moderate levels of bullying victimization along with increasing sexual harassment victimization are associated prospectively with greater alcohol use in adolescence. Findings highlight the importance of considering the cumulative, joint effects of multiple types of peer victimization on adolescent health outcomes.

PURPOSE: The age of drinking onset is a central concept for both policy and prevention of alcohol-related harm, yet evidence on the predictive value of the age of onset is lacking. This study compares alcohol outcomes of adolescents who started to drink early with those who started later, and tests if associations are moderated by other explanatory factors. METHODS: Data from a two-wave longitudinal prospective cohort survey with a Swedish nationwide sample of 4,018 adolescents aged 15/16 years at baseline (T1) and 17/18 years at follow-up (T2) were used. Outcome variables at T2 were Alcohol Use Disorders Identification Test (AUDIT)-C, risky drinking, and binge drinking monthly or more often. A vast number of explanatory factors at T1 were controlled for. RESULTS: Early drinking onset predicted later higher AUDIT-C scores (ß = 0.57, p value < .001), and higher probability of risky drinking (odds ratio = 1.95, 95% confidence interval = 1.56-2.44), and binge drinking (odds ratio = 1.38, confidence interval = 1.06-1.81), controlled for other explanatory factors. If binge drinking frequency at T1 was included, the associations remained for AUDIT-C and risky drinking, but not for binge drinking at T2. No significant interactions between early drinking onset and the explanatory factors were found. DISCUSSION: Early drinking onset predicts subsequent higher alcohol consumption in late adolescence. Adolescents who had an early drinking onset drank more after 2 years than their peers who started later. The age of drinking onset is an independent predictor of alcohol use outcomes, beyond the effect of age of binge drinking onset.

INTRODUCTION: The global alcohol industry sponsors social/music events targeting young people; however, existing literature focuses on Westernised contexts. Given the decline in young people's drinking in many Western countries, it appears that multinational alcohol companies are importing the strategies they have used in high-income countries to the Global South countries like Nigeria to recoup profits. This study aims to examine the Guinness Show- a free one-month annual music festival, alcohol marketing at the festival and the extent to which the event encourages diverse drinking practices among its attendees. METHODS: We observed the music festival before collecting data through 53 interviews and 3 focus groups (N = 26). Data were analysed to generate themes with the aid of NVivo 12 software. FINDINGS: Over 6000 participants attend the Guinness Show daily, and participants gave detailed descriptions of the music festival, alcohol marketing activities that occur in it and the drinking practices of attendees, indicating that they were highly knowledgeable of the event. The Guinness Show attracts famous music artistes and other entertainers. Therefore, young people attend to see them perform free of charge. However, diverse alcohol promotions (e.g., quantity deals, low prices, giveaways) that happen daily, the strategic use of young women as 'beer promoters', and the pleasure the event induces by fusing music/entertainment into alcogenic environments, encourage drinking and drunkenness. All the attendees drank alcohol, and some engaged in impulse buying, while many consumed excessively due to promotions (e.g., buy-two-get-one free), which facilitated intoxication and the loss of control. CONCLUSIONS: Guinness Nigeria organises the event for strategic brand communication, generating brand capital, and encouraging alcohol purchases and consumption among young people. Policymakers should reconsider self-regulation and implement national alcohol control policies and other public health interventions to restrain the alcohol industry from sponsoring such events.

BACKGROUND AND AIMS: Adolescent polysubstance use has been associated with adverse social and health outcomes. Our aim was to measure rates and transitions to polysubstance use during adolescence and identify factors associated with initiation and discontinuation of polysubstance use. DESIGN: Prospective cohort study. Multistate Markov modelling was used to estimate rates and identify correlates of transitions between substance use states. SETTING AND PARTICIPANTS: Adolescent-parent dyads (n = 1927; adolescents in grade 7, age ≈13 years) were recruited from Australian schools during 2010/11 (Wave 1). Adolescents were surveyed annually until 2016/17 (n = 1503; age ≈19 years; Wave 7) and parents were surveyed annually until 2014/15 (Wave 5). MEASUREMENTS: Alcohol, tobacco, cannabis and 3,4-methylenedioxymethamphetamine (MDMA) use outcomes were collected at Waves 3-7. Potential confounders were collected at Waves 1-6 and consisted of sex, anxiety and depression symptoms and externalizing problems, parental monitoring, family conflict and cohesion, parental substance use and peer substance use. Covariates were age and family socioeconomic status. FINDINGS: Few adolescents engaged in polysubstance use at earlier waves (Wave 3: 5%; Wave 4: 8%), but proportions increased sharply across adolescence (Waves 5-7: 17%, 24%, 36%). Rates of transitioning to polysubstance use increased with age, with few (<9%) adolescents transitioning out. More externalizing problems (odds ratio [OR] = 1.10; 99.6% confidence interval [CI] = 1.07-1.14), parental heavy episodic drinking (OR = 1.22; 99.6% CI = 1.07-1.40), parental illicit substance use (OR = 3.56; 99.6% CI = 1.43-8.86), peer alcohol use (OR = 5.68; 99.6% CI = 1.59-20.50) and peer smoking (OR = 4.18; 99.6% CI = 1.95-8.81) were associated with transitioning to polysubstance use. CONCLUSIONS: Polysubstance use in Australia appears to be rare during early adolescence but more common in later adolescence with low rates of transitioning out. Externalizing problems and greater parental and peer substance use are risk factors for adolescent polysubstance use that may be suitable intervention targets.

INTRODUCTION: The COVID-19 pandemic has significantly shaped the global landscape and impacted various aspects of individuals' lives, especially the behaviour of school-going adolescents regarding substance use. Among these substances, alcohol is the most predominant substance, particularly among school-going adolescents, who also are highly susceptible to harmful alcohol use, such as poor academic performance, psychiatric disorders and disrupted social lives. This review will synthesise the known prevalence estimates and associated factors of alcohol use among school-going adolescents in the Southern African Development Community (SADC) since the COVID-19 pandemic. METHODS AND ANALYSIS: We will perform a systematic review in line with the Cochrane Handbook for Systematic Reviews. We will systematically search for selected global databases (ScienceDirect, EbscoHost, PsycINFO and PubMed) and regional electronic databases (African Index Medicus, Sabinet and African Journals OnLine). Peer-reviewed literature published between 11 March 2020 and 10 March 2024 will be considered for eligibility without language restriction. All 16 countries of the SADC region will be included in the review. The Mixed-Methods Appraisal Tool checklist for quality appraisal will be used to appraise the methodological quality of the included studies. Depending on the level of heterogeneity, prevalence estimates will be pooled in a meta-analysis; narrative synthesis will be applied to describe the reported associated factors of alcohol use. ETHICS AND DISSEMINATION: We will not seek ethical approval from an institutional review board since the study will not involve gathering data directly from individual school-going adolescents, nor will it violate their privacy. When completed, the full report of this review will be submitted to a journal for peer-reviewed publication; the key findings will be presented at local and international conferences with a partial or full focus on (adolescent) alcohol (mis)use.

Negative affect (depression/anxiety) and alcohol use among Indigenous youth in Canada remain a concern for many communities. Disparate rates of these struggles are understood to be a potential outcome of colonization and subsequent intergenerational trauma experienced by individuals, families, and communities. Using a longitudinal design, we examined change in alcohol use and negative affect, and reciprocal associations, among a group of Indigenous adolescents. Indigenous youth (N = 117; 50% male; Mage=12.46-16.28; grades 6-10) from a remote First Nation in northern Quebec completed annual self-reported assessments on negative affect (depression/anxiety) and alcohol use. A Latent Curve Model with Structured Residuals (LCM-SR) was used to distinguish between- and within-person associations of negative affect and alcohol use. Growth models did not support change in depression/anxiety, but reports of drinking increased linearly. At the between-person level, girls reported higher initial levels of depression/anxiety and drinking; depression/anxiety were not associated with drinking. At the within-person level, drinking prospectively predicted increases in depression/anxiety but depression/anxiety did not prospectively predict drinking. When Indigenous adolescents reported drinking more alcohol than usual at one wave of assessment, they reported higher levels of negative affect than expected (given their average levels of depression/anxiety) at the following assessment. Our findings suggest that when Indigenous youth present for treatment reporting alcohol use, they should also be screened for negative affect (depression/anxiety). Conversely, if an Indigenous adolescent presents for treatment reporting negative affect, they should also be screened for alcohol use.

INTRODUCTION: The COVID-19 pandemic likely affected adolescent sexual behaviors and alcohol use, although how is not well understood. METHOD: Youth were sampled from the national, online longitudinal Growing up with Media study. They responded via text messaging to open-ended questions about how the COVID-19 pandemic may have impacted the sexual behavior and alcohol use of adolescents. Conventional content analysis summarized open-ended responses. RESULTS: 416 responses were analyzed from 335 participants (aged 15-30, US residents), 81 of whom provided data for both topics. Participants suggested that the pandemic affected some youths' sexual health precautions (increased and varying) and attitudes about sex (positive and negative). They discussed how adolescents met partners during the pandemic, including increased use of online platforms. Participants also suggested researchers investigate sexual risk in the realm of COVID-19 transmission and the practice of "safe sex." Many participants believed adolescents were drinking alcohol more as a result of the pandemic, both alone and with friends; however, others perceived adolescents were drinking less. Participants proposed researchers investigate adolescent drinking habits during the pandemic, as well as how this compares to before the pandemic and the type and quantity of alcohol consumed. CONCLUSIONS: Young people believe adolescent sexual relationships and drinking behaviors changed due to the pandemic, though how varied. Future research could examine the contexts and individual differences that shape these varying behaviors. Overall, this study highlights the importance of directly asking youth about their pandemic experiences and the diversity of views on how the pandemic has influenced adolescent behavior.

Parental monitoring behaviors are negatively associated with adolescent substance use. Yet, the processes explaining these associations are still unclear. The current study examined adolescents' knowledge of minimum legal drinking age laws and their perceived acceptability of underage drinking as potential mediators of the links between parental monitoring behaviors and youth alcohol use. The sample included 1154 Belgian adolescents (Mage = 16.34, SD = 1.33; 71% girls), who were recruited in Wallonia (54.9%) and in Flanders (45.1%). Path analyses revealed that higher parental rule setting, but not solicitation, was related to lower alcohol use. Acceptability of underage drinking mediated this link, but not knowledge of the laws. Results suggest that beyond laws regulating the minimum legal drinking age, alcohol use prevention programs should consider the importance of parental rule setting and youth's perceived acceptability of underage drinking.

BACKGROUND: Drug and alcohol use before the age of 14 is associated with adverse outcomes over the life course. While previous studies have identified numerous sociodemographic characteristics associated with youth substance use initiation, few have examined the relationship between behavioral characteristics, such as childhood aggression, and substance use initiation in adolescence. METHODS: This longitudinal study consisted of 2985 children from the Future of Families and Child Wellbeing Study. Aggression was measured using primary caregiver report when the children were about the age of 9 and cigarette, alcohol, and marijuana use was measured using the child report when the children were age 9 and age 15. Separate multivariable Poisson regression models were fitted for each substance use initiation outcome. RESULTS: Childhood aggression was positively associated with the initiation of cigarette and marijuana use in adolescence (aRR = 2.3 [95% CI = 1.5,3.4] and aRR = 1.3 [95% CI = 1.1,1.6], respectively). Childhood aggression was not associated with adolescent alcohol use initiation (aRR = 1.2 [95% CI = 0.9,1.5]). CONCLUSIONS: The presence of aggressive behavior in childhood was associated with the initiation of cigarette and marijuana use in adolescence. These results may be used to identify children at higher risk of cigarette and marijuana use, who may benefit from additional monitoring for substance use initiation.

Youth who are behaviorally aggressive and victimized by their peers comprise a significant population with specific risks and vulnerabilities relative to substance use. The goals of the current study were to examine the roles that youth aggression and peer victimization play in determining the timing of alcohol and marijuana use initiation and the frequency of use 5-years later in a sample of at-risk, aggressive youth. 360 youth (Mage= 10.17 years; 65% boys, 35% girls; 78.1% African American, 20.3% Caucasian, 1.4% Hispanic, and 0.3% other) recruited for a prevention program for at-risk youth were followed for 5 years (4th - 9th grade). Cox PH regressions were conducted to predict timing of alcohol and marijuana use initiation. Zero-inflated negative binomial regressions were used to predict frequency of alcohol and marijuana use 5 years later. Results showed that peer victimization inferred decreased risk of alcohol use initiation. However, this effect was only observed for youth with relatively moderate, and low levels of aggression. Findings suggest that differences in youth aggression and victimization interact to predict distinct outcomes, suggesting the need for a more comprehensive approach when working with aggressive youth who have experienced peer victimization.

RESUMO Objetivo: analisar os indicadores de consumo e exposição a bebidas alcoólicas entre escolares brasileiros em 2019 e compará-los aos de 2015. Método: estudo transversal com dados da Pesquisa Nacional de Saúde do Escolar (PeNSE), realizadas em 2015 e 2019. Em 2019, analisaram-se os indicadores referentes ao consumo e à exposição a bebidas alcoólicas, estratificadas por sexo, faixa etária, dependência administrativa, unidades da federação e região geográfica. Estimou-se as prevalências e os respectivos intervalos de 95% de confiança (IC 95%). Resultados: houve aumento na experimentação de bebidas alcoólicas antes de 13 anos (30,6% em 2015 para 34,6% em 2019); sofrer embriaguez na vida (27,2% em 2015 para 47,0% em 2019) e ter problemas com amigos devido ao consumo de bebidas alcóolicas (9,3% em 2015 para 15,7% em 2019). Todos os indicadores foram mais prevalentes entre meninas, exceto beber em binge e episódios de embriagues, que não tiveram diferenças entre os sexos, bem como foram mais elevadas entre estudantes mais velhos. Os episódios de embriaguez e ter amigos que ingerem bebida alcoólica foram mais prevalentes entre escolares de escolas públicas, enquanto o consumo de bebidas alcoólicas pelos pais e ter tido problemas com suas famílias ou amigos devido ao consumo de bebidas alcoólicas foram mais elevados em estudantes de escolas privadas. Conclusão: evidenciaram-se elevadas prevalências de experimentação, consumo e exposição a bebidas alcoólicas, mostrando que grande parcela dos adolescentes brasileiros se encontra exposta a uma carga evitável de morbimortalidade decorrente do consumo e exposição ao álcool.
RESUMEN Objetivo: analizar los indicadores de consumo y exposición a bebidas alcohólicas entre los estudiantes brasileños en 2019 y compararlos con los de 2015. Método: estudio transversal con datos de la Encuesta Nacional de Salud Escolar (PeNSE), realizada en 2015 y 2019. En 2019 se analizaron los indicadores referidos al consumo y exposición a bebidas alcohólicas estratificados por sexo, grupo de edad, dependencia administrativa, unidades federativas y región geográfica. Se estimó la prevalencia y los respectivos intervalos de confianza del 95% (IC 95%). Resultados: aumenta la experimentación con bebidas alcohólicas antes de los 13 años (30,6% en 2015 a 34,6% en 2019); sufrir borracheras en la vida (27,2% en 2015 a 47,0% en 2019) y tener problemas con los amigos por el consumo de alcohol (9,3% en 2015 a 15,7% en 2019). Todos los indicadores eran más frecuentes entre las chicas, excepto el consumo compulsivo de alcohol y los episodios de embriaguez, que no presentaban diferencias de género, además de ser más elevados entre los estudiantes de mayor edad. Los episodios de consumo de alcohol y el hecho de tener amigos que beben bebidas alcohólicas fueron más frecuentes entre los estudiantes de la escuela pública, mientras que el consumo de alcohol por parte de los padres y el hecho de haber tenido problemas con sus familias o amigos debido al consumo de alcohol fueron mayores en los estudiantes de las escuelas privadas. Conclusión: se evidenció una alta prevalencia de experimentación, consumo y exposición a bebidas alcohólicas, mostrando que una gran parte de los adolescentes brasileños está expuesta a una carga evitable de morbilidad y mortalidad resultante del consumo y exposición al alcohol.
ABSTRACT Objective: to analyze the indicators regarding consumption of and exposure to alcoholic beverages among Brazilian schoolchildren in 2018 and compare them to those from 2015. Method: a cross-sectional study conducted with data from the 2015 and 2019 National School Health Survey (Pesquisa Nacional de Saúde do Escolar, PeNSE). In 2019, the indicators referring to consumption of and exposure to alcoholic beverages were analyzed, stratified by gender, age group, administrative system, Federation Unit, and geographical region. The prevalence values and their respective 95 confidence intervals (95% CIs) were estimated. Results: there was an increase in trying alcoholic beverages before the age of 13 (from 30.6% in 2015 to 34.6% in 2019); being drunk in their lifetime (from 27.2% in 2015 to 47.0% in 2019) and having problems with friends due to alcohol consumption (from 9.3% in 2015 to 15.7% in 2019). All the indicators were more prevalent among the girls, except for binge drinking and drunkenness episodes, which presented no differences between the genders and were also higher among older students Episodes of drunkenness and having friends who drink alcohol were more prevalent among students from public schools, while consumption of alcoholic beverages by parents and having had problems with their families or friends due to alcohol consumption were higher in students from private schools. Conclusion: high prevalence of experimentation, consumption and exposure to alcoholic beverages was evidenced, showing that a large number of Brazilian adolescents are exposed to an avoidable burden of morbidity and mortality resulting from consumption of and exposure to alcohol.

O uso precoce de tabaco e álcool associa-se à maior morbimortalidade e manutenção desse consumo na vida adulta. Esta tese investiga o papel de fatores domiciliares e familiares sobre o início precoce do uso dessas substâncias entre adolescentes. Os dados analisados são do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA), que investigou 74.589 adolescentes de escolas públicas e privadas, com idades entre 12 e 17 anos, residentes de 124 municípios com mais de 100 mil habitantes no país. O primeiro manuscrito teve como objetivo estimar o efeito da presença de fumantes no domicílio sobre o início mais precoce de tabagismo entre adolescentes. O segundo manuscrito teve como objetivo estimar o efeito da composição familiar sobre o início mais precoce de tabagismo e do uso de álcool entre adolescentes. Em ambas as análises foram usados Modelos de Regressão de Cox não ajustados e ajustados por um conjunto de variáveis com intuito de controlar vieses de confundimento. Os Hazard Ratios estimados no manuscrito 1 mostraram um aumento de 51% (IC95%: 31%-65%) na chance de um adolescente não fumante e exposto ao tabaco em casa começar a fumar mais precocemente do que aquele que não convivia com tabagistas no domicílio. Nos resultados do segundo manuscrito observou-se uma influência importante da composição familiar sobre a precocidade de início do uso de tabaco e álcool entre adolescentes. Segundo os Hazard Ratios estimados, houve um aumento de 68% (IC95%: 50%-89%) na chance de um adolescente não fumante que não residia com ambos os pais iniciar o uso de tabaco antes de um adolescente que residia com pai e mãe. Quanto àqueles que residiam apenas com a mãe ou apenas com o pai, esse aumento foi de 46% (IC95%: 32%-60%) e 54% (IC95%: 28%-84%), respectivamente. Em relação ao início do consumo de bebidas alcoólicas, observou-se um aumento de 35% (IC95%: 21%-52%) na chance de um adolescente que não bebe e não reside com pai e mãe de iniciar o uso de álcool mais precocemente do que aqueles que residiam com ambos os pais. Quanto aos adolescentes que residiam apenas com a mãe ou apenas com o pai, esse aumento foi de 22% (IC95%: 17%-28%) e 36% (IC95%: 24%-50%), respectivamente. O terceiro manuscrito teve como objetivo investigar o uso conjunto de tabaco e álcool através de análises de coocorrência e de agrupamento, assim como descrever a relação temporal do início do uso das duas substâncias entre adolescentes tabagistas e usuários de álcool. Para a análise de agrupamento foram obtidas razões entre os valores observados (O) e esperados (E) de uso de tabaco e álcool. Na amostra total a razão O/E foi 3,51 (IC95%: 3,39-3,65) indicando o agrupamento do uso dessas substâncias. Já a Razão de Chances de Prevalência foi de 14,7 (IC95%: 12,4-17,4). A maior parte dos usuários (45,2%) de ambas as substâncias iniciou pelo uso de álcool. Nossos resultados reforçam as propostas de que ações preventivas não devem estar focadas em cada droga isoladamente, e devem incluir não só o adolescente, mas também seu universo familiar.
Early use of tobacco and alcohol is associated with increased morbimortality and maintenance of their use during adulthood. This thesis investigates the role of household and family factors on adolescents' early onset of these substances. The data analyzed are from the Cardiovascular Risk Factors Study (ERICA), which investigated 74,589 adolescents from public and private schools, aged between 12 and 17 years old, living in 124 municipalities with more than 100 thousand inhabitants in the country. The first manuscript aimed to estimate the effect of the presence of smokers in the household on the earlier onset of smoking habit among adolescents. The objective of the second manuscript was to estimate the effect of family composition on the earlier onset of smoking and alcohol use among adolescents. In both analyses, unadjusted and adjusted Cox Regression Models were used to control for confounding variables. The Hazard Ratio estimated in manuscript 1 showed a 51% increase (95% CI: 31%-65%) in the chance that a nonsmoking adolescent exposed to tobacco at home would start smoking earlier than one who did not live with smokers. The results of the second manuscript depicted an important impact of family composition on the early onset of tobacco and alcohol use among adolescents. According to the estimated Hazard Ratios, there was a 68% increased chance (95% CI: 32%-60%) that a nonsmoking adolescent who did not live with both parents would initiate tobacco use earlier than an adolescent living with both parents. As for those who resided with only the mother or only the father, the increase was 46% (95% CI:32%-60%) and 54% (95%CI: 28%-84%), respectively. Regarding the onset of consumption of alcoholic beverages, there was a 35% increase (95% CI:21%-52%) in the chance of an adolescent who does not drink and does not reside with both parents to initiate alcohol use earlier than those living with the mother and the father. As for adolescents living only with the mother or only the father, this increase was 22% (95%CI: 17%-28%) and 36% (95%CI: 24%-50%), respectively. The third manuscript investigated the concurrent use of tobacco and alcohol through co-occurrence and clustering analyses. It also described the temporal relationship between the onset of tobacco and alcohol use among adolescents consuming both substances. For the clustering analysis, we calculated ratios between observed (O) and expected (E) values of tobacco and alcohol use. In the total sample, the O/E ratio was 3.51 (95% CI: 3.39-3.65), indicating the clustering of the use of these substances. The prevalence odds ratio was 14.7 (95% CI: 12.4- 17.4). Most of the users (45.2%) of both substances started with the use of alcohol. Our results reinforce the proposal that preventive actions should not be focused on each drug separately and should include the adolescents and their families.
